STEEL-PLATE-RIVET- -IOLE-SPACING TABLE.

Specification of Letters Patent. Patented Dec. 16, 1919.

- Application filed. June 1, 1918. Serial No. 237,829.

To all whom it may concern;

Be it known that I, LEO F. COLL, a CllBlZBli of the United States,residing at Baltimore,

in the State of Maryland, have invented certain new and usefulImprovements in Steel- Plate-Rivet-Hole-Spacing Tables, of which thefollowing is a specification.

This invention relates to improvements in steel-plate-rivet-hole spacingtables and is especially adapted for use in connection with thepreparation of plates for ships.

The object of the invention is to provide a table of such a constructionthat the plates carried thereby may be fed to the die in such a mannerthat the rivet holes can be punched on a curve, a straight line, on anydesired angle, or staggered, as desired.

The invention consists of the novel construction and arrangement of theparts and combination of parts hereinafter more fully set forth in thefollowing specification and pointed out in detail in the appendedclaims.

In the accompanying drawings,

Figure 1 is a plan view of my invention showing one end of the base anda part of the carriage and plate-table.

Fig. 2 is a continuation of Fig. 1 and shows the other end of the base,carriage and plate-table.

Fig. 3 is a vertical section of Fig. 1 taken on the line X X thereof.

Fig. 4: is a front side elevation of Fig. 2.

Fig. 5 is a vertical section on the line Y- Y of Fig. 1 and shows theposition ofthe plate as it is fed to the die.

Fig. 6 is an enlarged detail section of one of the screws, and itsconnecting mechanism, for adjusting the curvature or angle of theplate-table guide rails.

Fig. 7 is a sectional plan View of Fig. 6 taken on the line ZZ.

Fig. 8 is an enlarged detail view of the wheel and mechanism foroperating the carriage along the base.

Fig. 9 is a front elevation of Fig. 8, the plate-table being omitted.

Fig. 10 is a plan view of Fig. 9.v

Fig. 11 is an enlarged detail view of the tracks and rollers at the endsof the platetable.

Referring to the accompanying drawings, forming part of thisspecification, and in which like reference numerals designate like partsthroughout the several views thereof, 1 designates a number of I-beamsupon which are secured two I-beams 2 and 3 at 3 the drawings.

right angles thereto; said I-beans 1, 2 and 3' forming the base of themachine. Extending-across the base at intervals are a number ofangle-irons 4t the rear ends of which are secured to the I-beam 2 andthe front ends project through the I-beam 3. Upon the upper surface ofthe angle-irons 1 are secured guide-plates 5 which serve as guides orrails for the blocks 6 and 7. The blocks 6 are provided with grooves 8in each side into which the guide-plates 5 pr0-- ject, and are alsoprovided with vertical apertures 9 through which the shafts 10 of theyokes 11 project; said shafts 10 being adapted to oscillate in theblocks 6 and are held therein by the pins '12. The said yokes 11 areeach provided with a block 13 held therein by the bolt 14 and have aslot 15 extending down from the top thereof which is undercut on eachside at the bottom for the reception of the guide-rails 16, which latterare made of two pieces each having its lower end bent at right angles tohold them in the slots 15." The impinging surfaces of the two piecesforming the guide rails 16 are flat to allow them to slide against eachother in the blocks 13 when the curvature or angle of said guide-rails16 is being changed. The said guide-rails each have a flange at itslower end at one side to hold them in the blocks 13, and beingformed oftwo pieces can be made very thin to give them greater flexibility.

The blocks 7 are forward of the I-beam 3 and are also provided withslots in each side thereof into whichthe guide-plates 5 project and areconnected to. the blocks 6 by the metal plates 17, the latter each beingprovided with a metal piece 18 riveted thereto at 19 and projectingupwardly at its front.

end and having an aperture 20 therethrough and a slot 21 extendingforward from the aperture 20. The pin 22 projects through the piece 18and the plate 17 and has its end resting in the aperture 23 of the block7. V

The said pin 22 is provided with a small pin 24. at one side whichpasses through the slot 21 when the pin 22 is beingpassed through theaperture 20 and which prevents said pin 22 from coming out when placedin said aperture and turned, as shown in Fig. 6 of The said blocks 7 areeach mounted on a threaded shaft 25 the rear ends :of which have theirbearings in the blocks 26 back of the I-beams 3 and-their front endsprovided with a hand wheel 27 ihe shafts 25 are each provided with acollar .28 between the plates 29 and 30 which latter are secured to theends of the angle-irons d. The turning of the hand-wheel 27 causes theblocks 7 and consequently the blocks 6 to move backward or forward forthe purpose of adjusting the curvature or angle of the guide-rails 16.At the side of each of the blocks 7 a line 31 on the uppe surfacethereof adapted to register with the gage at the side of said blocks 7,said gages 32 being secured to the upper surface of the guide-plates 5by means of the screws The carriage is formed of two angle-irons and 35and a number of short transverse angle-irons 36 which rest upon and aresecured to the inwardly-pro jecting flanges of the angle-irons 3st and35. On the outer surfaces of the angle irons 3a and are secured therollers 87 which rest upon the rails 38 on the upper surface of theangle-irons 2 and 3. A metal strip 39 is provided at the outer surfacesof the rollers 87 and projects down over the sides of the rails 38. Thesaid rollers 37 have their hearings in said strips 39 and the sides ofthe angle-irons 3% and 35, which latter also project down over the sidesof the rails 38, thus preventing any sidewise movements of the carriageas it is moved along the rails. On the lower surface of the angle-iron34: is secured a rack e0 in mesh with the geanwheel l1 on the inner endof the shaft 42, the latter being mounted in the bearings a3 and ski andis provided with a large hand wneel on its outer end. By turning thesaid wheel -15 the carriage, through the medium of the gearwheel -l-1and rack 40, will be moved along the rails 38 to the right orleft, asdesired. Securedvto the plate 39 at the front of the machine is anotched spacing bar 46 which travels with the carriage and cooperateswith the dog at? for spacing the rivet holes in the plate being prmched.The said dog 4-7 operates vertically in the slot -18 in the upper end ofthe casting A) bolted to the front oi the I-bearn 3 and prevents anylateral. u'r-ovemcnt of said dog 4L7 and also holds it in perfectalinement. The said dog a? is carried on the upper end of the rod 50 andis held norn'ially out of engagement with. the notches of the spacingbar e6 by the coiled spring 51. The lower end of the rod 50 is pivotedto the short lever 52 which latter is secured to the inner end of theshaft 53 mounted in the bearings 54 and 55 on the side of the Z-loeam 56and provided with a treadle 57 on its outer end. When the foot of theoperator is upon the treadle 57 the dog 47 will rest upon the upper edgeof the spacing bar Q6 and when the wheel 45 is turned the carriage, andconsequently the spacing bar 46, will be mover along the rails until thenext notch of the spacing bar 46 comes under the dog 47 when thepressure on the treadle e? by the operator will cause the said dog 4:?to fall into the notch and lock the carriage, at the same time causlngthe treadle 57 to strike the button 58 which closes the circuit andopera es the punch 59. The treadle 5'? is then released and the carriageadvanced to the next notch by turning the wheel h"), when the sameoperation is repeated and continued until all the holes have beenpunched in the plate 60. l Vhen it is desired to change the spacing ofthe holes in the plate being punched, the spacing bar 46 is removed andanother spacing bar inserted having notches the spacing of whichcorresponds to the spacing of the holes to be punched in the plate. Theplate-table is composed of two channel-irons 61 connected by a number ofshort transverse channelirons 62 which project above the channelirons 61and upon which the plate rests, and a bottom plate 63 which extends theentire length of the said plate-table. The under side of the saidplate-table is provided at intervals with transverse rails 64 directlyabove and in line with the rails 65 on the flanges of the angle-irons36. The said rails at the end of the plate-table are closer t0- gether.Between the rails 6d and 65 are rollers (36 which have, their bearingsin the plates 67. hese plates 67 travel back and forth with the rollers66 and project beyond the rails or and 65 at the top and bottom and holdthe said rollers thereon. The platetahle thus resting on the rollers 66is adapted to be moved back and forth at right angles to the travel ofthe carriage in order that the plate may be punched on a curve or angleopposite to that described by the guide-rails 16. At each end of theplate-table are two Z-bars 68 the upper angles of which are providedwith a number of apertures 69, and a short plate 70 which also hasapertures in each end for the reception of the bolts 71 and is adaptedto be adjusted along the Z bars 68 to accommodate the varying widths ofplates to be punched. The plate 60 to be punched rests upon the uppersurface of the channel-bars (32 and is held by the screwcla .ips 72 ateach end which said clamps are each provided with a pin 7 3 adapted tofit into one of the apertures 79c in the plate 70. The said apertures74.! may be in line, or staggered, so that two lines of holes can bepunched in line or staggered in the plate 60 by changing the pin 73 ofthe clamps 72 from one to the other of the holes 74 after one line ofholes has been punched in the plate 60. Secured to the under surface ofthe platetable at each end thereof is a bearing 75 having a central.aperture 76 into which a shaft 77 projects, said shaft 77 being providedwith across-head 78 on its lower end which rests upon the upper edge ofthe guide-rails 16. Two rollers 7 9 are revolu'bly secured to the lowersurface of the crosshead 78 and have their peripheries impingv angle ofthe guide-rails 16. There are two i guide-rails 16 and they are both setat the same curvature or angle and one end :of the plate-table isconnected, as above described, to one guide-rail 16 and the opposite endto the other guide-rail 16, both of which guide.- rails can be set toany curve or angle desired by turning the hand wheel 27 which operatesproper the blocks 7 and 6 upon which latter the guide-rails 16 arecarried. The line of holes punched in the plate 60 as it is fed to thedie will have a curvature or angle of the same degree but opposite tothat described by said guide rails 16. The guide-rails 16 are eachformed of two pieces so that they may readily yield when being adjustedthe fiat impinging surfaces of said two pieces being adapted to slideagainsteach other during the adjustment of said guide-rails 16 Theoperation of the device is as follows:

The guide-rails 16 having been set to the curvature or angle, through.the mechanism heretofore described, the plate 60 to be punched issecured in position on the plate-table. The operator then turns thewheel 45 causing the carriage to move toward the other end of the basecarrying the plate-table and plate with it and as the nextnotch of thespacing bar 46 comes under the dog 17 the treadle 57 is pressed downlocking the said carriage and at the same time causing the treadle tostrike the button 58 closing the circuit which causes the die to punchthe plate 50. The treadle 57 is then released and the carriage movedforward another notch when the same operation is repeated and continueduntil one line of holes has been punched in the plate 60. At the sametime the carriage is moving along the rails on the base the platetableis caused to follow the curvature or angle of the guide-rails '16through the mechanism described, thereby causing the punching of theplate 60, to be done at the same degree of curvature or angle butopposite to that of the guide-rails 16. 7

When the guide-rails 16 have been set for the punching of any particularor standard pattern or design, or for a certain size ship, a record ofthe same may be kept in accordance with the gages 32 so that the samedesign or pattern may be reproduced at any time.
